To all 'whom t may concern.'

Be it known that I, FREDERICK EGGE, a citizen of the United States,residing in the city of Bridgeport, county of Fairfield, and State ofConnecticut, have invented certain new and useful Improvements inSash-Pulleys; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to certain improvements in the construction andassembly of sash pulleys and has for its object to provide a device ofthis description which shall be exceedingly simple, strong, and readilyassembled without the use of any tools or special securing devices, andwith these ends in view my invention consists in certain details ofconstruction and combination of parts hereinafter fully described andthen particularly pointed out in the claims which conclude thisdescription.

In the accompanying drawing Figure 1 is a face elevation of my improvedpulley- Fig. 2 an inside elevation of the face plate- Fig. 3 a plan viewof the housing as it appears when assembled-Fig. 4 a side elevation ofthe pulley-Fig. 5 a section at the line as', w, of Fig. 6, and Fig. 6 arear elevation of the completed pulley.

Similar numerals of reference denote like parts in the several figuresof the drawing.

1 is the face plate provided with countersunk perforations 2 for theaccommodation of screws to fasten the pulley within its mortise, saidface plate having a centrally disposed elongated opening 8 for theaccommodation of the pulley wheel, as will be hereinafter described. Theedges of this face plate are bent rearwardly as shown at 4 at rightangles to the plate itself so as to provide a strengthening rib whichlatter also contributes toward the proper fitting of the face platewithin its mortise. The opposite sides of the bent edge 4 are lanced,and the lanced portions are driven inwardly so as to provide skeletonears 5 that are spaced from the rear face of the plate 1.

The pulley housing proper is composed of two similar housing sections 6,7 and these sections have extending from their lower outer edges flanges8, 9, and these flanges are lanced and the lanced portions are forcedrearwardly so as to provide shoulders 10,11.

In assembling my improved sash pulley, one of the housing sections isplaced in position against the rear of the plate 1 with its flangeimmediately beneath the ears 5 at one edge of the plate, and with theshouldered portions of its flange abutted against said ears, and thenthe other housing section is similarly assembled with respect to theears at the other side of the plate, and when these housing sections arethus assembled they will appear as is illustrated in Fig. 6. The pulleywheel 12 is then placed within the housing and suitably journaledtherein by means of a pin 13 which extends through the sides of thehousing sections and through the pulley itself, the extremities of saidpin being suitably headed or riveted against the outside faces of saidsections. I

The ears 5 are separated from the rear face of the plate 1 by a spacesutlicient to accommodate the flanges 8, 9, and therefore these earswill serve to confine the housing sections 6, 7 firmly to the face platewhile the shoulders 10, 11, prevent any displacement of the sections 6,7, lengthwise of said plate.

From the above it will be observed that the face plate and the housingsections are assembled without the use of any tool or any fasteningdevices such as screws or riveted portions. I claim 1. In a sash pulley,the combination of a face plate having its outer edges bent rearwardlyat right angles to the face of said plate and provided with inwardlyextending ears that are suitably spaced from the rear face of saidplate, complementary housing sections having flange portions providedwith shoulders projecting therefrom, said portions adapted to beconfined between said ears and the rear face of said plate wit-h saidshoulders and ears in abutment, and the pulley suitably journaled withinsaid housing sections.

9.. In a sash pulley, the combination of the face plate having its outeredges bent rearwardly at right angles to the face of said plate andhaving opposite sides of said bent portions lanced and driven inwardlyand a pulley Wheel journaled Within said to form ears that are spacedfrom the rear housing,` sections. 10 face of said plate, complementaryhousing In testimony whereof I aiiix my signature sections havingflanges extending from their in presence of two Witnesses.
